Streaming Stick+ (3810X) and 5 Ghz channel 132-144

Jump to solution

So I went and purchased a Streaming Stick+ specifically so I could use my 5 Ghz SSID and get away from our heavily overpopulated and slow 2.4 Ghz channels.

I'm using a Portal router that supports DFS, allowing me to actually have a channel not used by anyone else. But apparently Roku has decided not to support this, as the stick does not find my 5 Ghz network. Am I correct in this conclusion?

If so I have to say I'm pretty disappointed. This will be the first device I've encountered that won't connect to the DFS channels. Multiple laptops, phones, tablets, even a Kindle Fire all connected fine but the Roku will not.

This defeats entirely the most significant advantage of 5 Ghz Wi-Fi. The ability to have an SSID not sharing channel space with other users.

Like I said, I fully understand DFS. I have been using it now for nearly a year and a half and have never had an issue, with the multiple devices I've already named. And I've streamed on most of them.

This issue was resolved by returning the stick to Amazon for a full refund. I will find another device that meets my needs.

Roku will not connect to the DFS channels. That is by design.

I'm not sure why Roku would design their device this way. For anyone who has gone to the effort to use DFS channels, the Streaming Stick+ is about as useful as a Roku Express or Premier.

The channels assigned to the 5 GHz band between 49 and 148 are shared with other uses such as military, radar, and weather. These channels are termed DFS (dynamic frequency selection) and routers are supposed to automatically switch to a different channel if they detect one of these channels is in use in your area. Roku devices don't support these DFS channels and many home routers don't even include them.

I'm aware of all of that. But some of us have routers that do, and to date, the Roku is the first device I've encountered that won't use them. I have had 3 or 4 different Android phones, an Android tablet, two Kindle Fire's, 3 laptops and a couple of HP printers that all worked just fine on the DFS channels.

My only real point is that it's a shame that the Roku will not. If I wanted to use it, I'd have to set my route to one of the few non DFS channels and share that bandwidth with my neighbors. Instead of having bandwidth of my own.

There is no guarantee you wouldnt encounter "sharing" or "non-interference" on a DFS channel - just the opposite, that being the nature of DFS: 

1) Expect your Auto-assigned DFS channel assignment to change due to interference (with a period of disconnectivity for most clients), and

2) expect your Manual-assigned DFS channel to drop entirely (device offline). 

3) Additionally, when automatically re-assigned, the new channel may or may not be a DFS channel.

4) Furthermore, there are a lot of false positives for the regular (required) interference checks on DFS channels, thus creating a lot of channel reassignment and disconnectivity.

So, ultimately, you may experience more connectivity problems using/enabling DFS than not/without.

You can then understand why a streaming device would avoid making connections in scenarios that anticipate increased/frequent periods of disconnectivity due to interference/channel reassignment.
